Billionaire entrepreneur, Douw Steyn plans to develop a residential area that will be bigger than Sandton.

Douw Steyn, one of South Africa’s richest men, will be making a permanent mark on the Johannesburg landscape by creating a residential estate bigger than the whole of Sandton.

Mr Steyn City will sit snugly between Dainfern and Diepsloot. Diepsloot – situated in Johannesburg – sprang up as a cheap labour response to the development of the luxury Dainfern Estate in the same area.

At 900h, Mr Steyn City will be roughly three times the size of Dainfern Estate and development will cost a jaw-dropping R6 billion before construction on residences has even started.

According to designs, a wooded parkland will account for half the estate, with roughly 11 000 residential units built around it.

Apart from a private hospital, two private schools, and multiple office parks, the estate will sport a 70km track for off-road cycling, and a 42km route for runners.

The main premise of the estate’s design is to limit the need for motor vehicles as much as possible.

At the heart of it lies Palazzo Steyn — a private residence for Mr Steyn, which is rumoured to have cost more than R150m.

It has been reported that Mr Steyn’s house has a garage for 33 cars, a wine cellar, seven bedroom suites, and is situated above a man-made lake.
